Scratch Build – In Progress ECI 12+ (Single Stage Phase Cooler(

Another project on the bench, a nice quiet and small phase cooler.

Goals?
Low cost (~$600 or less)
Subzero (Around -20C or lower) load on an i7 sized load (or more!)
Small footprint
Solid (steel base frame)
Decently quiet
Low power consumption (Sub 300W)
Upgradeable features (Full case, digital temperature display)

Specifications:
1/5hp Copeland r404a compressor
120mm Chilly1 Blue Condenser with 38mm fan (~100cfm)
18" Braided flex line (Extrable flex, without risk of tearing!)
Copper Spiral Evaporator and new Universal Mount
Full Insulation kit
Double H frame, solid steel, MIG welded, ground, then painted

Pictures up in a few

Desuperheater coil brazed, as well as the main suction entity.


Steel triple H frame it seems, to help suspend the condenser. Might end up switching to 3/4 or even 1/2" steel. This 1" is way over the top.


I call this a Harvey Dent shot, one face is cleaned, one face still oxidized.


The bend of this flexible line, a steel corrugated line under copper/brass alloy braid. Able to withstand lots of pressure and still flex well.

 

YAY, another phase cooler. I will be watching this one also .

 

An update!
Frame spot welded, ground, and heading for sand-land before some paint.

Single Stage sits on it, have some nice rubber feet as well.
Total drop in unit, solid frame, I love it.

 

Nice evaporator and mount ordered, took a bit of a while.
But should arrive this week so I can finish this up.
Oh and grinded and sprayed the frame!
Now to drill and mount some bolts and what not.

 

Watching... again.

 

what sort of evap design are you using?

 

Going to use a classic spiral, sand blast it, and a few other modifications.

 

Mount arrives with evaporator!
Nice, universal, pre made insulation, what more could you want?

 

That mounting plate looks great, looks like a giant CPU block retention bracket lol.

 

NoL do you rock your work on XS forums? Either way I love phase systems and hopes yours goes all to plan. Good luck!

 

I did for a long time, the forums are no longer home to the phase kings. They went overclock and commercial I feel a while ago.

 

Lineset brazed and pressure tested.

 

true. but they're still boss at minimalist watercooling systems

nice brazing work by the way. and your layout is very clean

 

They do know their water, I'll give them that.

 

Custom accumulator brazed and fitted.
The internal design is NOT an empty cavity, but contains an item to cause baffling and stop linear flow.

 

hey looking nice so far, is this a bench rig or will it be in a case?

 

It's going to be just on the steel frame I've shown. Keeps the cost down should I find a buyer. But I may give a shot at welding up a decent "cage" when it's done. Might see how cheap I can go, 1/2" or 3/4" steel or what not. Still more then sturdy.

Pressure testing now.

 

cool

 

And she's holding just fine, guess I've still got it
Onto vacuuming.
Ice tomorrow most likely or a bit later tonight! Time to wire.
